Description

Technical Field

[0001] The invention belongs to agricultural machinery, and mainly relates to a mechanical seed meter suitable for seeding operations similar to spherical seeds. Background Art

[0002] Currently available mechanical eye-shaped and scoop-wheel seeders are not suitable for row seeding. Currently, row seeding still relies on the decades-old external groove wheel seeder. Due to its simple structure and easy adjustment, this type of seeder remains in use today and is used in strip fertilization operations. In recent years, with the advancement of science and technology, agricultural users are hoping for more seeders utilizing different principles and structures for mechanized crop row seeding. This would provide users with more options and leeway for different crop varieties, meeting the needs of mechanized agricultural row seeding. Summary of the Invention

[0003] The purpose of the present invention is to address the problems existing in the above-mentioned prior art, and in combination with the actual needs of mechanized crop seeding operations, to develop an elastic hose squeeze-type spherical seed seeding device. Through the squeeze-type transportation and seeding principle, it achieves the goals of novel, unique and reasonable structure, strong applicability to spherical seeds, good seeding operation quality and high operation efficiency.

[0004] The purpose of the invention is achieved in this way: an arc-shaped elastic hose and a vibration block are sequentially installed on the same radius position of the inner wall surface of the bottom wall of the circular groove-shaped shell along the circumferential direction, a seed inlet is opened on the tube wall position of the seed inlet end of the circular arc-shaped elastic hose, the seed inlet end head of the circular arc-shaped elastic hose is closed, and the seed drop port is arranged on the seed discharge end head of the circular arc-shaped elastic hose, and a seed box and a seed guide tube are sequentially relatively equipped on the outer wall surface of the circumferential side wall of the circular groove-shaped shell, a seed filling port and a seed outlet are opened on the seed box, the seed outlet is connected with the seed inlet, and the seed guide tube is connected with the seed drop port; a motor is fixed on the side wall of the circular groove-shaped shell through a motor frame, The power disc is fixed on the motor shaft of the motor. The power disc and the circular groove shell are coaxially arranged in the groove cavity of the circular groove shell. A swing limit frame is fixed on the inner end face of the power disc and located in the groove cavity of the circular groove shell. The wheel frame is hingedly mounted on the swing limit frame so as to be able to swing back and forth. The compression spring is arranged between the power disc and the wheel frame. The two ends of the compression spring are respectively in extrusion contact with the power disc and the wheel frame. The roller is mounted on the wheel frame. The roller is in extrusion contact with or out of extrusion contact with the arc-shaped elastic hose and the vibration block in turn, thereby constituting an elastic hose extrusion type spherical seed drill seeding device.

[0005] The invention utilizes the good flowability of spherical seeds and adopts rollers to squeeze and convey the arc-shaped elastic hose filled with spherical seeds and a seed-discharging structure to complete the row sowing operation of the spherical seeds. It has the characteristics of novel, unique and reasonable structure, good row sowing operation quality, high operation efficiency, and strong applicability to spherical seeds, and has opened up a new structural scheme for mechanical crop seeding devices.

[0013] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. An elastic hose squeeze-row type spherical seed drill seeding device, an arc-shaped elastic hose 7 and a vibration block 10 are installed in sequence along the circumferential direction on the same radius position of the inner wall surface of the bottom wall of the circular groove-shaped shell 1, a seed inlet 14 is opened on the wall portion of the seed inlet end of the arc-shaped elastic hose 7, the seed inlet end of the arc-shaped elastic hose 7 is closed, and a seed drop port 8 is arranged on the seed discharge end end of the arc-shaped elastic hose 7, a seed box 12 and a seed guide tube 9 are sequentially relatively equipped on the outer wall surface of the circumferential side wall of the circular groove-shaped shell 1, a seed filling port 13 and a seed outlet 15 are opened on the seed box 12, the seed outlet 15 is connected to the seed inlet 14, and the seed guide tube 9 is connected to the seed drop port 8; a motor 3 is fixed on the side wall of the circular groove-shaped shell 1 through a motor frame 11, a power disc 2 is fixed on the motor shaft of the motor 3, and the power disc 2 is connected to the circular groove-shaped shell 1 The power disc 2 is coaxially arranged in the groove cavity of the circular groove-shaped housing 1. A swing limit frame 16 is fixedly installed on the inner end surface of the power disc 2 and in the groove cavity of the circular groove-shaped housing 1. The wheel frame 6 is hingedly mounted on the swing limit frame 16 so as to be able to swing back and forth. The compression spring 5 is arranged between the power disc 2 and the wheel frame 6. The two ends of the compression spring 5 are respectively in a compression contact fit with the power disc 2 and the wheel frame 6. The roller 4 is mounted on the wheel frame 6. The roller 4 is in a compression contact fit or out of compression contact fit with the arc-shaped elastic hose 7 and the vibration block 10 respectively.

[0014] During operation, the spherical seeds in the seed box 12 fall into the tube cavity of the arc-shaped elastic hose 7 through the seed outlet 15 and the seed inlet 14 in turn. At this time, the rotating motor 3 drives the power disc 2 to drive the roller 4 to rotate around the center line of the motor shaft of the motor 3 through the swing limit frame 16 and the wheel frame 6. When the roller 4 rotates to the seed inlet end of the arc-shaped elastic hose 7 and begins to contact the arc-shaped elastic hose 7, the roller 4 compresses the arc-shaped elastic hose 7 and squeezes the spherical seeds filled in the tube cavity of the arc-shaped elastic hose 7 from the seed inlet end to the seed discharge end, and is discharged through the seed drop port 8 and enters the seed guide tube 9, completing the row sowing operation of the spherical seeds, and the operation is continuously cyclically operated in sequence. When the roller 4 completes a row sowing operation and loses contact with the arc-shaped elastic hose 7, the roller 4 contacts the vibration block 10. Under the cooperation of the vibration block 10 and the compression spring 5, the roller 4 causes the entire seed meter to vibrate continuously, thereby ensuring that the spherical seeds in the seed box 12 are reliably and smoothly filled into the arc-shaped elastic hose 7 from the seed outlet 15 and the seed inlet 14, thereby improving the flow performance of the spherical seeds.
